AUTOMOBIL-E ANDVRIM LOCK;

To all whom it may concern; 'l

Be it known that I, JOSEPHl ZAHLER, 'a at of Wisconsin, have invented certain new and useful Improvements in Automobile- Tire y andyRim Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to 'new and useful improvements in.automobi1e` tire and rim locks, and has for its primary object the provision of means which w11l preventthet ofa tire and its rim when carried as an extra onan automobile, and also may be employed for supporting the tire and rim on the `automobile in lieu of the ordinary tire carrier, or the device may be employed in conjunction with a tire carrier. .i

Another object of ,this invention 1s the provision of means which will permit easy and quick removal of the tire and rim when desired and when supporting the latter will preventsan unauthorized person from removing the same. l p ,y

A further object of this invention is the provision o'f an automobile tire and rim lock ofthe above stated character which will be simple, durable and efficient, and which may be manufactured and sold ata comparatively low cost.v f r i With-these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts as .will be hereinafter more fully Y described and claimed.- y y For aco'mplete understanding of my invention, reference -is to be ,had to the following description and accompanying drawings,

I in which:-

formed integrally therewith a lock casing 5 a lock 6 of a conventional construction -actuated through the mediumpf a key. vThe lockcasing 5. has formed 'integrally there` with, a bracket 7 adapted to be either secured to a tire holder or directly to anA automobilel by 4non-removable fasteners.

' Upon .the .rear edgeof the base 4 is formed aj retaining fiange 8f p rovided with screw threaded openings toreceive set` bolts 9 that have swivelconne'ction with a tire clamp'lor The tire clamp or iron 10 coceiving and supportingthe tire 1, as clearly shown in-Figure 2. The tire`clamps or irons 10 and 11 maybe of desired'shape as for instance. as shown in Figures 2 and 8. In

`Figure 2 the clamps or irons are shown as being shaped to conform toa ltire having a smooth tread while the irons-or clamps in Figure 8 are shaped to. conform to the contour of "a non-skid treadv of a tire. The base 4 1s adapted'to have the rim 2 su porting the tire rest thereon and is provide with acut- `out portion 12 adjacent the retaining flange 84 for tthevreception. of a base 13 formed on or iron 10. The base 13 is `shaped tocon lerm tothe rim 2 andone of its retaining an'ges and Vseat within the cutout portion 12 partially underlyingthe rim 2.

The lock .3 consists of a base 4 which has'y The base 13l is` provided lwith ycountersunk openingsto receive the' heads 14 formed on -the set bolts 9 whereby said setbolts are swivelly connectedto lthe tire iron or clamp `.10 and will notntevfere withl the base 13 thereof conforming to the curvature of the rim and one of its bead flanges.

The base 4 is provided with a chamber 15 in which is slidably mounted a stem 16 and said chamber opens outwardly on one. side of the base 4 to receive an arm 17 formed integrally with the tire clamp or iron 11. One end of the stem 16 is reduced and apertured and disposed between spaced ears 18 formed 0n the arm 17.

The ears are pivotally connected by rivets or bolts 19. The hinged connection between the stem 16 and the arm 17 established by the rivet 19 and said ears are confined within the chamber 15 when the device is nin tire supporting and holding position preventing the tire clamp or iron 11 from being swung away from the tire. The stem 16 is provided with a slot 2O engaged by a stop 21 carried by the base 4, for limiting the outward movement of the stem 16 and which is urged outwardly of the chamber by means of expansion spring 22. stem whenfreed from a locked position will permit said stem to pass sufficiently outwardly ofthe chamber 15 to expose the hinge between itself and the arm 17 so that the tire clamp or iron may be swung away from the tire l. o The stem 16 lis provided with a notch y23 adapted to be engaged by the .locking bolt 24 of the lock 6 to retain the stem in al retracted position 'and for holdingv the hinged connection between the stem and the arm 17 within the casing and consequently holding lthe tire clamp or iron 11 in engagement with the tire.

The tire clamp or iron 11 is providedl with a base 24, shaped to conform to the other bead flange of the rim'2 and has Vformed integrally therewith the arms 17.

' The ,lock casing 5 is equipped with a hinged cover 25 normally urged into a, closing position by means of a spring 26 and' is adapted to vconceal the lock 6 and thereby exclude dust, dirt and other foreign matter from the lock.

The stop 21 is in the form of a screw and is threaded'into an opening formed in the base 4 and which communicates with the chamber and ext-ends through the outer face of saidbase so thatvthe screw 21 can be removed land replaced when the tire and rim have been removed from the device. With the tire and rim positioned upon the device it is impossible to remove the screw 21 until after the tire clamp or iron 11 has been freed and the rim removed.A .In-o'perationthe tire and rim are positioned upon the base 4 when the tire clamp The slot 20 in the" or iron 11 is in an open position and after lthe proper positioning of the tire and rim lock or unlock the device it will be always necessary to first adjust the setv bolts 9 so as to permit the rim and tire to have a slight transverse movement with relation `to the base 4. The adjustment ofthe tire clamp or iron 10 is limited away from the tire by the retaining iiange 8 and .the adjustment allowed'to the tire clamp or iron 10 is not sufficient to permit the rim 2 to become disengaged from the holder or permit the rim 2 to be moved out or beyond the base 1 3 of said tire clamp or iron. n

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes` in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is:

A tire and rim lock comprising a support having a transverse chamber opening outwardly through one side thereof and having its other end closed, a flange formed inthe other side of the support and the latter having a recess, a tire and rim engaging element seated in said. recess, means adjustable on said flange to force said element against one end wall of said recess, a stem in said chamber and having a notch and a recess, a spring between the stem and the closed. end of the chamber, a projection carried by the support and fitting in said second'recess, a second rim and tire engaging element having an extended portion into the stem, and a locking means carried by the support toengage the notch to retain the stem and a part of the extended portion in the chamber against the action of the spring.

In testimony whereof I aiiix my signature in presence of two witnesses.
